Backend Engineer @Arealis | Java & Golang | Kafka | Event-Driven Microservices | Spring Boot

About

I am a Backend Engineer with hands-on experience building scalable, high-throughput, event-driven systems using Java, Golang, Apache Kafka, and Spring Boot. I specialize in microservices architecture, streaming pipelines, and production-grade backend platforms for financial and enterprise applications. At Arealis Network, I build backend services implementing transactional outbox patterns, exactly-once message delivery, and idempotent processing to ensure data consistency across distributed systems. I design Kafka topics, partitioning, and schema strategies to support low-latency, high-volume workloads and develop secure webhook APIs with signature verification, retries, and DLQ support. Previously at Cisco Systems, I contributed to a legacy event transformer backend service using Java, Kafka, and Flink, implementing webhook features, payload transformations using Jolt-spec, and feature-flag-based controlled rollouts across INTG, QA, and Production environments.I am passionate about building robust, reliable, and maintainable backend systems, improving observability with tools like Kibana and Grafana, and collaborating with cross-functional teams to deliver high-quality production-ready software.

Work experience

Back End Developer at Arealis, Jan 2026 - Present · 7 mos, Pune, ◆ Build backend services in Golang with transactional outbox patterns and exactly-once delivery for financial transaction pipelines. ◆ Design and maintain Kafka topics, partitioning, and schema versioning for ordered, high-throughput event processing. ◆ Implement idempotent Kafka consumers with DLQ, retry, and replay mechanisms for robust backend processing. ◆ Develop secure webhook APIs with signature verification, replay protection, and fault-tolerant error handling. ◆ Ensure backend reliability by handling failure scenarios, message duplication, and partial processing. ◆ Collaborate with product, platform, and security teams to deliver production-ready features meeting performance, scalability, and compliance standards.

Software Developer at Cisco, Nov 2024 - Nov 2025 · 1 yr 1 mo, Bengaluru, ◆ Contributed to a legacy event transformer backend service using Java, Kafka, and Flink, responsible for transforming large upstream event payloads into optimized webhook events. ◆ Implemented multiple webhook features to deliver client-specific requirements while maintaining payload efficiency. ◆ Used Jolt-spec transformations to map and reduce payload size dynamically. ◆ Rolled out new webhook features behind feature flags, tested across INTG, QA, and load environments before production deployment. ◆ Improved backend observability by integrating structured logs into Kibana dashboards. ◆ Collaborated with Product Security (PSIRT) and cross-functional teams to remediate vulnerabilities and ensure compliance.
